power supply and reset changes for the v5.19 series 

power-supply core:
  - init power_supply_info struct to zero
 
 drivers:
  - bq27xxx: expose data for uncalibrated battery
  - bq24190-charger: use pm_runtime_resume_and_get
  - ab8500_fg: allocate wq in probe
  - axp288_fuel_gauge: drop BIOS version from "T3 MRD" quirk
  - axp288_fuel_gauge: modify "T3 MRD" quirk to also fix "One Mix 1"

Merge tag 'for-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply

Pull power supply and reset updates from Sebastian Reichel:
 "Not much from the power-supply subsystem this time around, since I was
  busy most of the cycle. This also contains some fixes that I
  originally planned to send for 5.18. Apart from this there is nothing
  noteworthy.

  Power-supply core:

   - init power_supply_info struct to zero

  Drivers:

   - bq27xxx: expose data for uncalibrated battery

   - bq24190-charger: use pm_runtime_resume_and_get

   - ab8500_fg: allocate wq in probe

   - axp288_fuel_gauge: drop BIOS version from 'T3 MRD' quirk

   - axp288_fuel_gauge: modify 'T3 MRD' quirk to also fix 'One Mix 1'"

* tag 'for-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply:
  power: supply: bq24190_charger: using pm_runtime_resume_and_get instead of pm_runtime_get_sync
  power: supply: bq27xxx: expose battery data when CI=1
  power: supply: ab8500_fg: Allocate wq in probe
  power: supply: axp288_fuel_gauge: Drop BIOS version check from "T3 MRD" DMI quirk
  power: supply: axp288_fuel_gauge: Fix battery reporting on the One Mix 1
  power: supply: core: Initialize struct to zero
